OBJECTIVE:The aim of this study was to assess sensitivity and specificity of surrogate physical ability tests as predictors of criterion firefighting task performance and to identify corresponding minimum muscular strength and endurance standards. METHODS:Fifty-one (26 male; 25 female) participants completed three criterion tasks (ladder lift, ladder lower, ladder extension) and three corresponding surrogate tests [one-repetition maximum (1RM) seated shoulder press; 1RM seated rope pull-down; repeated 28 kg seated rope pull-down]. Surrogate test standards were calculated that best identified individuals who passed (sensitivity; true positives) and failed (specificity; true negatives) criterion tasks. RESULTS:Best sensitivity/specificity achieved were 1.00/1.00 for a 35 kg seated shoulder press, 0.79/0.92 for a 60 kg rope pull-down, and 0.83/0.93 for 23 repetitions of the 28 kg rope pull-down. CONCLUSIONS:These standards represent performance on surrogate tests commensurate with minimum acceptable performance of essential strength-based occupational tasks in UK firefighters.

目的:本研究的目的是评估替代体力测试的敏感性和特异性,以作为标准消防任务表现的预测指标,并确定相应的最低肌力和耐力标准。
方法:51名(男26名;女25名)参与者完成了三个标准任务(梯子抬高,梯子下降,梯子伸展)和三个相应的替代测试[最大重复坐姿(1RM),肩部推举; 1RM落座式绳索下拉;重复28 kg坐下的绳索下拉]。计算替代测试标准可以最好地识别通过(敏感性;真阳性)和失败(特异性;真阴性)标准任务的人员。
结果:最佳的灵敏度/特异度是:35 kg的肩部推举时为1.00 / 1.00,60 kg的拉绳器为0.79 / 0.92,23次重复28 kg的拉绳器为0.83 / 0.93。
结论:这些标准代表在替代测试中的性能,与在英国消防员中基于强度的基本职业任务的最低可接受性能相当。
